Black out a signature before sharing a scan
Stop your signature being lifted from a shared scan, privately.
A visible signature on a scan can be copied and reused to forge documents. If you need to share a signed page for its content, not its signature, you can black the signature out. This tool removes it on export, all in your browser, so the scan is never uploaded.

Why remove a signature on your device
A signature is a reusable credential. Redacting it in the browser means the version showing your signature is never uploaded where it could be lifted.
Frequently asked questions
Can the signature be recovered?+
No. On export the image under the box is deleted, so it cannot be copied or recovered.
Is my scan uploaded?+
No. Redaction runs in your browser and the file never leaves your device.
What if I need to remove a digital signature instead?+
For a signature field that locks the file, use Remove Signature; this tool blacks out a visible signature image.
Is it free?+
Yes, with no account.
